In order to determine the performance deterioration of latticed structures subjected to steel corrosion under atmospheric exposure; symptom-based reliability method employing stress evolutions of structural members as a primary symptom was presented; where the practical steel corroding process was replaced by the model gained from long term experimental results of steel exposed in corrosive environment. The Weibull model curve; fitted by the stress-time curve of the controlling member with its wall thickness decreasing constantly; was employed for symptom-based reliability analysis and lifetime prediction of latticed structures. Considering the discrepancy between symptom data from the practical health monitoring and those from the analytical results; the predictions of symptom-based reliability analysis were updated. The results from a case study show that the structural reliability and remaining useful lifetime drcrease year by year; based on the design reference under the consideration of the performance deterioration due to the single cause for damage. This conclusion grees with those published in previous papers;
